You history view is somehow broken.
I noticed this already a couple of times, but now I report, since I could verify that also with the latest revision 3355fc315757.
Here is my latest workflow as an example: I clicked on my MacHg repo and selected in History view I saw there were your incoming changesets, which I pulled right away NOW: none of the newly pulled changesets has been displayed in the History view I clicked on another repo and clicked back on MacHg and there the new changesets appeared, i.e. after pulling you did not update the view with the new data
Another way to see the missing update: Try to update your repo to another revision The information window will pop up and tell you what has changed * But the History view will be unchanged
BTW, THANKS FOR ADDING ME TO CREDITS! :)
